IEEE 1588 (PTP)
Precision Time Protocol (PTP) is enabled/disabled using the Ethernet configuration tool /ECT) in
PCM600.
PTP can be set to On , Off or Slave only . When set to Slave only the IED is connected to the PTP-
group and will synchronize to the grandmaster but cannot function as the grandmaster.
A PTP-group is set up by connecting the IEDs to a network and enabling PTP. To set one IED as the
grandmaster change Priority2 to 127 instead of the default 128.

PTP VLAN tag must have the same value in station clock and in the IED. The default value is set
The
to 0.
The PTP VLAN tag does not need to be the same on all access points in one IED. It is possible to
mix as long as they are the same for all devices on each subnet.
